Introduction

Every decision to take a vaccine to prevent an illness is essentially a decision that the short term expense and slight discomfort (and slight risk) is worth the improved chance of avoiding an unpleasant or potentially fatal illness. The following recommendations are based on the advice of international agencies such as the World Health Organization and the Centers for Disease Control in the United States, coupled with our local experience. Vaccine recommendations occasionally vary from Europe to North America, usually in regard to the exact schedule of giving the vaccine. The results of vaccination can be the same with different schedules.
The protection that can be gained from vaccines is variable, so remember that even if you have taken a vaccine you might still get the disease, although you will have greatly reduced your chances of getting ill.

1. For the Prevention of Hepatitis A:
Hepatitis A is acquired through ingestion of contaminated food or water. The Hepatitis A vaccine is a highly effective and safe with long lasting protection. It is given as a series of 2 shots with adequate protection 2 weeks after the first shot.  For Twinrix, the combined A and B vaccine given as a series of 3 shots, protection starts 2 weeks after the second dose. Nepali adults who used to be almost always immune to hepatitis A through clinical or silent infection in childhood may no longer be immune due to improved levels of personal hygiene and sanitation. It therefore makes sense to give this vaccine to Nepali adults who are not immune to hepatitis A. The vaccine offers protection even when given after exposure on account of the long incubation period of Hepatitis A. If you have had hepatitis A disease in the past, you will be immune for life and do not need the vaccine.

2. Prevention of Hepatitis B:
Hepatitis B Vaccine is a vaccine with high safety and efficacy. Hepatitis B is spread through direct contact with infected blood or through sexual contact. All adults and children are recommended to take this vaccine. Since there are no animal reservoirs of infection, an effort is being made to give hepatitis B vaccine to all humans, which would eventually eliminate the disease from the world. The regimen for hepatitis B vaccine is an initial injection followed by boosters at one month and six months. Rapid schedule is available for people with time constraints. Hepatitis B antibody levels do not need to be checked routinely for healthy adults. Health care workers, immuno-compromised persons can check levels 1- 2 months after the last dose of the hepatitis B vaccine. For persons with inadequate levels (<10 mIU/ml), further 3 doses of hepatitis B vaccine at 0, 1and 6 months are currently recommended.

3. For the Prevention of Typhoid Fever:

Typhoid fever is a prolonged febrile illness caused by infection with Salmonella Typhi bacteria. An almost identical illness, called paratyphoid fever, is caused by Salmonella Paratyphi. The organisms are passed in human feces, and acquired by eating contaminated food or water. The disease can make you very ill and the bacteria have become drug resistant. There are currently three different typhoid vaccines on the market – an oral typhoid vaccine using live organisms, a capsular polysaccharide and a conjugate injectable vaccine. At CIWEC Clinic, we currently stock only the typhoid conjugate vaccine TCV (TYPBAR-TCV/Bharat Biotech). Typhim Vi is a single injection with boosters required every two years. TCV is also a single injection and provides long term protection or booster doses may be given after 3 years. Both provide significant protection (55% – 85%) and these do not offer any protection against paratyphoid fever.

4. For the Prevention of Meningococcal infections:
Meningococcal infection can cause meningitis, which is a severe bacterial infection of the lining of the brain or a severe blood stream infection called meningococcemia. Meningococcal vaccines are safe, and highly effective. We currently stock Menactra, the quadrivalent vaccine consisting of serotypes A, C, Y, and W135. Protection from a single shot lasts 5 years as an adult. Quadrivalent vaccine is required for the Hajj, and is needed for college entry into the USA and for travel to the meningitis belt of sub-Saharan Africa. There is currently no recommendation for this vaccine for travel to Nepal.

5. For the Prevention of Japanese Encephalitis (JE):
JE is caused by a virus carried by culex mosquitoes in rural areas of southern Nepal or the Terai and in Kathmandu. JE virus can cause a severe and often fatal infection of the brain. There has been a single case report of JE in a French traveler to Nepal in 2012. Persons visiting Nepal particularly in the post-monsoon months of late July through early October and all residents of the Kathmandu valley are recommended to receive immunization against JE. At CIWEC we stock the inactivated vero cell vaccine JEEV.  Live SA 14-14-2 vaccine (CD-JEVAX) is currently only available through the Nepal Government program as part of routine childhood immunization.

6. For the Prevention of Rabies Encephalitis:
Rabies virus is transmitted by the bite/scratch of infected animals or from saliva contact with mucous membranes. The disease is present throughout Nepal, India, and Tibet and dogs account for >96% of human cases. Because of the delay between the bite and clinical illness, rabies vaccine and immunoglobulin can be given after a bite to prevent illness. This post-exposure series offers essentially 100% protection but it does take 2-4 weeks to complete the four shots plus the initial injection of rabies immune globulin (human or equine). For this reason, long-term travelers or foreign and local residents often take a pre-exposure series, consisting of 3 shots on days 0, 7, and 21- 28 days. These “pre-immunized” individuals require only two booster shots 3 days apart, if they are bitten by an animal. We highly recommend the pre-exposure series to everyone particularly children who may not report to their parents every contact with a stray animal or someone’s pet. World Health Organization (WHO) in April 2018 has stated that only 2 doses of vaccine on day 0 and 7 are required for pre-immunization but no long term data are available with this approach and several health authorities around the world are still recommending the 3 dose series. There are currently no recommendations for booster doses of rabies vaccine in travelers because the immune memory stays strong and reacts appropriately when vaccine is given after exposure. In immune-compromised persons, both vaccine and immunoglobulin are required to be given, even if the person is pre-immunized.

7. For the Prevention of Tetanus:
Tetanus bacteria can infect small wounds and cause a fatal infection. The risk is the same throughout the world. Most people would have received tetanus vaccine as primary series in childhood mixed with other vaccines. Single dose of TdaP (mixed with diphtheria and pertussis) is recommended as an adult to boost pertussis immunity, followed by Td (mixed with diphtheria) every 10 years.

8. For the Prevention of Polio:
Polio Vaccine: Several rounds of mass vaccinations of children under the age of 5 years against Polio have rendered Nepal polio-free since 2011. Almost all tourist and foreign residents have been vaccinated against this disease in childhood. Polio vaccine booster is not required for Nepal since Nepal is polio-free. Booster is required if you are coming in from polio endemic countries like Pakistan and Afghanistan.
9. For the Prevention of Cholera:

Cholera Vaccine: The risk of cholera to the foreign traveler or resident in Nepal is close to zero as has been shown by diarrhea research that we do every 10 years or so. Cholera is mainly spread by heavily contaminated water, or by certain sea coast animals that concentrate the bacteria (such as oysters). If you are conscientious in not drinking untreated water (or milk, which might be contaminated with water), you will have almost no chance of getting cholera. For persons volunteering in an outbreak situation when access to clean drinking water may not always be possible, cholera vaccination makes sense. We keep a small stock of the cholera vaccine Shanchol at CIWEC..

10. For the Prevention of the “flu”:

Influenza Vaccine: Influenza, or the flu is a viral illness that causes fever, muscle aches, cough, and misery for a number of days. The vaccine consists of killed particles of three different strains of influenza going around in the previous year, and can significantly cut your risk of getting sick with the flu. A single injection offers protection for about one year. There are outbreaks of Influenza A of the H1N1 variety in Nepal from time to time each year. CIWEC Clinic makes this vaccine available each year – usually in September-October. We recommend the flu vaccine for all persons >6 months of age annually.

11. For the prevention of Pneumonia:

Pneumococcal conjugate vaccine or Prevnar- 13:  Persons 65 years of age or older should receive one dose of PCV 13 followed by PPSV 23 (Pneumovax 23) one year later. If a prior dose of PPSV 23 has been received, PCV -13 should be given after one year. These vaccines should also be given to persons 19 through 64 years of age if they have no spleen, are immune-compromised, have CSF leak or cochlear implants. Single dose of PPSV-23 alone should be given after age 19 years in adults with chronic heart, lung or liver disease, diabetes, and smoking. Prevnar-13 is no longer recommended in the West for adults due to immunization as a child with Prevnar – 13. We will continue to recommend this vaccine to the Nepali adults.

12. For the prevention of Herpes Zoster

Herpes Zoster vaccine: VZV (Varicella Zoster virus) causes chicken pox in childhood. The virus continues to reside in the nerve ganglion and reactivates much later in life as a painful condition called Herpes Zoster. A recombinant Zoster vaccine called RZV or Shingrix can be given to persons >50 years of age to reduce the risk of Herpes Zoster and that of post herpetic neuralgia.  A live attenuated vaccine ZVL or Zostavax can also be used in persons >60 years of age. Currently we do not have these vaccines in stock.

13. Human Papilloma Virus or HPV vaccine:

It is for the prevention of genital warts in men and women and cervical cancer in women. HPV -9 is recommended for all persons from age 9 – 26 years.
